Title: Vehicle cleaning equipment
IPC: B60S3/06
Filed: 1972-06-30
Abstract: 1432772 Vehicle washing apparatus AVW EQUIPMENT Ltd 17 Aug 1973 [30 June 1972] 30672/72 Heading B7J Vehicle cleaning equipment comprises a rotatable horizontal brush 2 mounted in a frame for movement upward under the control of a first means and downward under the control of a separate second means, one means (the first as shown) being responsive to the extent to which vehicle contact resists brush rotation and the other means (the second) being responsive to the extent to which the weight of the brush is borne by the vehicle, i.e. the weight of the brush less any uplift due to engagement of the brush on the surface of the vehicle being cleaned. The parameter for sensing resistance to brush rotation during upward movement of the brush is the current drawn by an electric motor 3 rotating the brush 2, which is carried by end plates 4<SP>1</SP> of a carriage 4. The end plates are suspended by an extensible section 11 consisting of springs 11a which hang from a yoke 10. When the brush 2 hangs freely and is not in contact with a vehicle, the springs 11a are extended and the brush weight is taken by chains 12 between the plates 4<SP>1</SP> and yoke 10 and further chains 5 extending from the yoke 10 over driven sprockets 7 to counterweights 9. While the brush is in suitable engagement with the vehicle, part of its weight is taken thereby and the length of the springs 11a is reduced, thus increasing spacing 15 between a proximity switch 13 on the yoke 10 and an L-shaped member 14 carried by plate 4<SP>1</SP> and preventing supply of current to a motor 8 for driving the sprockets 7. As brush/vehicle engagement decreases, the brush hangs freely and spacing 15 reduces until the switch 13 triggers supply to the motor 8 so as to lower the brush 2. Vertical side brushes 1 are also provided, and the frame carrying the brushes is movable along the length of a stationary vehicle during the washing operation.

Title: Improvements in or relating to microphones or the like
IPC: H04R9/08
Filed: 1933-11-08
Abstract: 428,144. Sound receiving and transmitting devices; diaphragms ; acoustic horns and attenuators. WILLANS, P. W., Bush House, Aldwych, London. Nov. 8, 1933, Nos. 31030/33 and 7395/34. [Class 40 (iv)] [See also Groups XXII and XXXVIII] To avoid distortion of sound waves at the microphone or receiver diaphragm, the diaphragm chamber 1 is fitted with a sound inlet pipe of small diameter and relatively great length open to the air, and the formation of stationary waves in this pipe is prevented by providing a sound - absorbing chamber into which all the sound waves will pass and from which no part of them will return. With an electrodynamic microphone, the absorbing chamber and the inlet pipe are at opposite sides of the diaphragm, but with an electrostatic microphone they are on the same side. The openings from these two chambers to the diaphragm chamber are of the same size. The outer end of the inlet pipe should be small enough to avoid directional effects, and for high quality transmission should not exceed about 1 inch in diameter. As an example, an electrodynamic microphone may be fitted with a brass inlet pipe 3ft. in length and tapering logarithmically from #in. diameter at the outer end to <3>/16 in. at the diaphragm chamber, giving an increase of response of six decibels, and with an absorbing chamber in the form of a pipe 20ft. long and <3>/16 in. diameter containing one strand of 4-ply knitting wool, this pipe being of lead except for a 2ft. length in brass at the inner end. As shown in Fig. 2, the diaphragm chamber 1 is mounted on polepieces 2 forming radial arms of an annular permanent magnet 3, and is fitted with an inlet pipe 4 and with an absorbing pipe 5 which is coiled around a drum 6. The diaphragm 19, Fig. 3, is a thin strip of aluminium foil and is held at one end between brass blocks 12, 20, and the other end is held in contact with a brass plate 14, 15 and insulated from the casing by ebonite blocks 16, 22. For use as a transmitter, the circuit including the diaphragm, the casing and the plate 15 includes the primary of a transformer, the secondary being connected to an amplifier. For use as a receiver, serving for example as a standard of reference, an audio-frequency current is passed through the diaphragm and the end of the pipe 4 is inserted in the ear. A device for positioning the diaphragm, shown in Fig. 5, comprises a base 28 which may be secured temporarily to a flange 31 on the base 7 of the diaphragm chamber, and a screwactuated carriage 29 which supports the diaphragm 19 at the correct height. One end of the diaphragm is first secured by the block 20, the carriage 29 is adjusted until the diaphragm is slightly slack, and the diaphragm is then secured at 31<a> by the block 22 and severed from the surplus foil on the carriage.

Abstract: 1466592 Stapling fibres NEUMUNSTERSCHE MASCHINENUND APPARATEBAU GmbH 12 July 1974 [30 Aug 1973] 31099/74 Heading D1F A fibre-stapling machine comprises a roller cage and an encircling cutter head which are relatively rotatable about a common axis and between the peripheral rollers and inwardly directed knife-edges of which a filamentary tow is fed from the interior of the cage is pressed and cut. An endless conveyor may envelope the cage and be drawn inwardly between two rollers to form an inner loop travelling over guide rollers and encircling the means for introducing the tow. Cut fibres may be removed through the machine casing centrifugally or pneumatically by suction. The machine shown comprises a stationary cutter head formed by opposed circular plate 1 and ring 2 carrying knives 5 slidably seated at their ends in equiangularly spaced radial slots and clamped between annular, angle-section fittings 3 and 4. A roller cage 11, mounted on the shaft 7 of electric motor 8, is formed by a face-plate 10 and ring 12 which are connected by a spacing cylinder 13 with a longitudinal gap 14 and carry at their peripheries the ends of axles 15 and 16 of freely rotatable rollers 17 and 18. Inside cage 11 a hub 9 carries an eyelet 19, through which the tow is guided, and an endless band 22 which is guided by rollers 18, 20, 21, to include a tensioned loop. Wave-form cam edges 24 and 25 engage opposite ends of successive knives to impart antiphase reciprocation of adjoining knives. In a stapling operation, the tow of filaments 34 is first pulled manually into the cage, threaded through eyelet 19 and the gap 14 and is secured at 35. As the cage rotates, the tow winds in layers on the band 22 with rollers 17, 18, rolling on the inside thereof, until the knife-edges engage the outermost layer and cutting proceeds. In a modified machine Fig. 3 (not shown) the cutter-head (to which the leading end of the tow is secured) rotates about a stationary cage 11 and the tow is layered from the inside outwardly. In a tow feeder 31, a continuously variable transmission (not shown) allows the cage or head to gain slightly on the feed rollers 32.
